To display chat history with each turn as a separate widget under Inputs, you need to ensure that each message in the chat is properly structured and stored as individual spans with attributes for each message. According to the <https://docs.arize.com/phoenix/tracing/how-to-tracing/setup-tracing/setup-sessions#%3ARiikd9uucqfkvfa%3A|Phoenix documentation>, you should use semantic conventions to set attributes for each message, such as `llm.input_messages` and `llm.output_messages`. This allows you to track each message separately and display them in the UI.
Ensure that each message is stored with attributes like `role` and `content` for both input and output messages. You can use the `setAttribute` method to set these attributes for each span. For example, you can structure your code to set attributes for each message as follows:
```
span.set_attribute("llm.input_messages.0.message.role", "user")
span.set_attribute("llm.input_messages.0.message.content", "Hello!")
span.set_attribute("llm.output_messages.0.message.role", "assistant")
span.set_attribute("llm.output_messages.0.message.content", "Hi there!")
```
